Syracuse, N.Y. -- Nearly 39,000 New Yorkers signed up for coverage on the state health insurance exchange Monday, the official deadline for enrolling in Obamacare.

The state said the last-minute surge pushed the total number of New Yorkers who have enrolled since Oct. 1 to 865,487. Among that group, 412,101 people enrolled in private health plans and 453,386 individuals enrolled in Medicaid, the government health insurance plan for the poor.

While Monday was the official deadline, the state said it will give additional time to individuals and families who applied for coverage, but did not complete the enrollment process on time. The state said all applications and enrollments in health plans must be done by the end of the day on April 15.

The next open enrollment period will begin Nov. 15, 2014.

Aside from those who qualifiy for the April 15 extension, the only people who can sign up for coverage before the next open enrollment period begins are individuals who experience major changes in their families or employment. Qualifying events include getting married or divorced, gaining a dependent, losing employer insurance or permanently moving into New York state. Individuals eligible for Medicaid can enroll anytime.

The state said the health insurance exchange is on track to meet or exceed its enrollment goal of 1.1 million by the end of 2016.
